The credit card processor we use (uc_linkpoint_api) requires that the order ID be passed as part of the transaction. The problem is that if someone's card is declined that order ID is now in Linkpoint's system and can't be used again. So, if the user were to click to click the Back button and change their CC# it would still not be able to process the order because it would detect a duplicate Order ID. So, my question is how would I reset the order ID after a declined transaction? Can I just increment it to the next available ID in uc_orders or is it also a session variable?
thanks
